Advanced Search

Allows specified searches for Substances, Molecular Formulas, Element Systems, CAS Registry Numbers and Properties in the relevant fields. Typing effort for query formulation is reduced by suggestions of terms (Speed Typing) showing available content.

Substances field: The speed-typing list also offers CAS Registry Number and Molecular Formula next to Substance Name in brackets. Element Systems can be typed with dash (the minus key) between the individual elements. The field supports case sensitive input; please use capital letters or spaces to mark the beginning of a new element symbol.

Your Query combines all search strings from the other fields of the Advanced Search page into a Boolean query that you can either submit as is or adapt to your needs before submitting it to the search engine.
